These are actually developmental abnormalities but can closely mimic the behavior of benign vascular neoplasms. They may be composed of abnormal aggregations of arterioles, capillaries, or venules.

Features

Telangiectasias can result in nevus flammeus (port-wine stain), which is a flat birthmark on the head or neck that spontaneously regresses. A port-wine stain, if present, will grow proportionately with the child. There is a high association with Sturge-Weber syndrome, a nevus formation in the skin supplied by the trigeminal nerve and associated with glaucoma, meningeal angiomas, and mental retardation. Finally, spider telangiectasias are a radial array of tiny arterioles that commonly occur in pregnant women and in patients with hepatic cirrhosis. In men, they are related to high estrogen levels secondary to liver disease.

Associated conditions

Telangiectasias may occur in a number of diseases, including (ICD-10 codes are provided):

  • (M34.1) CREST syndrome (a variant of scleroderma)
  • (I78.0) hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome)
  • (G11.3) Ataxia telangiectasia

Treatment

Telangiectasias are often treated with laser or IPL therapy.
